text: Brazing is a joining process in which a filler metal is melted and drawn into a capillary formed by the assembly of two or more work pieces.  The filler metal reacts metallurgically with the workpieces and solidifies in the capillary, forming a strong joint.  Unlike welding, the work piece is not melted.  Brazing is similar to soldering, but occurs at temperatures in excess of .  Brazing has the advantage of producing less thermal stresses than welding, and brazed assemblies tend to be more ductile than weldments because alloying elements can not segregate and precipitate.
  Brazing techniques include, flame brazing, resistance brazing, furnace brazing, diffusion brazing, inductive brazing and vacuum brazing.
